Who Should You Contact in Tempe About Cracks in Walls?

When you start seeing cracks in your walls, it’s easy to think they’re just part of a home’s natural settling. But in Tempe, those cracks could be signaling something deeper—issues with your foundation or stem wall. I’m James Belville, owner of Concrete Repairman LLC, and our team has helped hundreds of Arizona homeowners correctly identify and repair wall and foundation cracks before they turned into major structural problems.

What Causes Cracks in Walls to Appear in Tempe Homes?

Tempe’s dry desert climate might seem harmless, but the expansive clay soil beneath your home tells a different story. Changes in moisture levels cause the ground to expand and contract, creating stress on your foundation. Over time, this can lead to:

• Vertical cracks from foundation settlement
• Horizontal cracks from soil pressure or water intrusion
• Diagonal cracks caused by shifting or uneven load distribution
• Rust stains and flaking concrete due to rebar oxidation within the stem wall

Once water seeps into the concrete, the embedded steel (rebar) begins to corrode and expand. This process slowly pushes apart the surrounding concrete, leading to visible cracks in your walls or near your home’s base.

When Should I Be Concerned About Wall Cracks?

Not every wall crack means danger—but some are clear red flags. If you notice any of the following, it’s time to reach out for a foundation inspection:

• Cracks wider than 1/8 inch or that continue to grow
• Horizontal cracks running along the lower walls
• Chipping or flaking concrete at the base of the stem wall
• Doors or windows sticking or no longer closing properly
• Water stains or rust marks near the foundation

These signs often point to foundation movement, rebar corrosion, or stem wall deterioration, all of which require prompt attention. At Concrete Repairman LLC, we specialize in accurately diagnosing these issues—not just patching the surface, but repairing the underlying cause.

Who Is the Right Professional to Contact for Wall Cracks in Tempe?

You should always contact a licensed foundation repair contractor with proven experience in structural concrete restoration. General handymen or untrained crews might offer quick cosmetic fixes, but without addressing the rebar oxidation or moisture intrusion, the problem will resurface—and usually worse. Our team at Concrete Repairman LLC is licensed, bonded, and insured. We’re one of the few specialists in Arizona trained to use structural hydraulic grout patches—a high-performance method for repairing foundation and stem wall cracks. We take pride in every inspection and repair, providing homeowners with clear explanations, digital assessments, and custom repair plans that last.

How Do We Inspect and Repair Cracks in Walls?

Our process begins with a thorough foundation inspection around your property. We assess the type of cracks, identify their causes, and check for hidden corrosion or moisture intrusion. Here’s what the repair process typically involves:

• Removing damaged concrete to expose corroded rebar
• Treating or replacing the rebar to stop future oxidation
• Filling and sealing cracks with hydraulic grout for structural reinforcement
• Applying waterproof coatings to protect against moisture intrusion
• Restoring the stem wall and exterior finish for long-term durability

By addressing both the cosmetic and structural aspects, we ensure the wall cracks won’t return—and that your foundation remains strong for years.

What’s the Difference Between Wall Crack Repair and Foundation Repair?

Many homeowners are surprised to learn that wall cracks often indicate deeper foundation problems rather than just cosmetic issues. While minor drywall cracks can occur due to temperature shifts or normal settling, larger cracks that extend through the stem wall or foundation slab usually signal structural movement or rebar corrosion. Understanding this distinction is essential to maintaining your home’s stability and safety.
At Concrete Repairman LLC, we specialize in both wall crack repair and foundation repair, addressing not only the visible damage but also the root cause beneath it. Our services include stem wall repair and waterproofing, slab crack repair and leveling, rebar oxidation treatment, and tension tie and J-bolt replacement—all designed to restore your home’s foundation integrity and prevent further damage. If you’re unsure whether your cracks are surface-level or structural, we’ll inspect, explain, and recommend the most effective long-term solution right on the spot.

Can Early Inspections Save You Money?

Absolutely. Catching a foundation problem early can save thousands of dollars in future repairs. Many homeowners wait until cracks grow or walls start separating—but by that point, corrosion and soil movement may already have spread. Scheduling a foundation inspection every five years (or sooner if you notice cracking) can help prevent costly reconstruction later. Our team at Concrete Repairman LLC provides free assessments and detailed digital reports, so you’ll always understand your home’s condition and the most cost-effective repair plan.
